1954 Press Photo General Electric's new reactor compared to the size of a button

Schenectady, New York, July 9 -- Tiny reactor, smaller than a shirt button, is used by General Electric engineers to amplify signals so feeble that an air conditioner could be controlled by the effect of a lighted cigarette on the temperature of a room. Small as it is, the reactor consists of 2 fine copper wires wound around a circular core of highly sensitive magnetic material. It is used in applying a new principle under which weak energy signals in the form of force, light, movement and temperature are amplified by making electrical current "beat" like your heart only faster. Photo measures 8.5 x 10.5 inches. Photo Is dated 1954.
